Tomatoes were introduced to Europe by the Spaniards in the sixteenth century. They are rich in antioxidants, especially carotenoids such as betacarotene and lycopene. They contain vitamins C and E, and so protect the heart, the circulatory system and the body against cancer. They are low in sodium and high in potassium, thus are helpful with conditions such as high blood pressure and fluid retention.
Canned tomatoes lose very little of their nutritional value, so always keep some in the larder. The lycopene contained in tomatoes protects men against prostate cancer. Tinned tomatoes, tomato sauce, tomato ketchup and sun-dried tomatoes are all important nutritionally. They protect men and women against heart disease. I love cherry tomatoes! So much nicer than sweets!
